I have two datagrids in a master/detail relationship. I will call them dgMaster1 and dgDetail1. Datagrid dgMaster1 holds student's biographic information. dgDetail1 holds several addresses that pertain to that student. I have a 'save' button in each row of dgMaster1 that I want to use to save the student and his/her address. The 'save' button should be enabled or disabled based on the validation of a student's biographic data as well as the address in dgDetail1.
I want the 'save' button to be disabled if there are any validation error in the selected row in dgMaster1 or any of the rows in dgDetail1. This validation functionality currently works for the student's biographic data in the selected row of dgMaster1. However, I am unable to find any resource that would enable me to validate all the rows in dgDetail1 as a block. That is, I want to determine if there are any rows in dgDetail1 that has a row that has any error.
I am using MVVM pattern
